How do we actually trade cards?

[biz]

if I want to accept someone's trade offer what steps do we take to trade so that noone gets robbed?
as far as I know the game only has cash on delivery, not cards on delivery

is there a way to trade through the website?

The site only offers you a way to find people to trade with. It's up to you to discuss the terms of the trading. I did a lot of trades already with people I found on the site and never had any problems. However, to make sure you're not getting robbed or something, you can both send cards with COD. So if the other guy didn't send you the cards, at least you keep the money.
